I usually LOVE John Lennon's vocals, but Elvis' singing is better on this song. BUT, Ringo's drumming is way better than the original.

Yeah, I much preferred the drums in the Beatles version, I didn't actually pick the drums as Ringo at first, very different to most of his usual drumming. The Elvis version has that real boom-chicka-boom-chicka feel of the 50's, I love Cash but I'm not a massive fan of that style of drumming.
